Loc.—Otekaike (type) and Queenstown. Types in the Canterbury Museum.

This species differs from L. neozelanicus Archey by its darker colouring, its much stouter anal legs, and by the form of the prosternal teeth.

Paralamyctes validus Archey.

Paralamyctes validus Archey, Trans. N.Z. Inst., vol. 49, p. 314, 1917. P. dubius Archey, ibid., p. 314.

A series of these forms has now been examined, and it is clear that they are the same species, the differences previously noted as separating them being those normal between slightly immature and fully-grown forms. The South Island representatives of this species do, however, differ slightly from the North Island forms, but the differences are scarcely of specific rank. There are also small sex variations to be seen in each variety, which may be expressed as follows :—

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Sex Length
of Antennae.
Coxal Pores. Prosternal Teeth
North Island 18 mm. ½ body-length 4444/4444 or 4555/4555 9 + 9 or 10 + 10.
" 19 mm. ⅓ " 5666/5666 "
South Island 20 mm. ½ " 3444/3444 8 + 8 or 9 + 9.
" 20 mm. ⅓ " 4555/4555 "

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

P. dubius therefore forgoes its specific rank and is retained only as a variety of P. validus, differing from it by the reduction in the number of coxal pores and prosternal teeth. Small specimens (10–13 mm.) of both forms have coxal pores 2222/2222, and 5 + 5 or 6 + 6 prosternal teeth, those of 15 mm. length having coxal pores 3333/3333, and 6 + 6, 7 + 7, or 6 + 7 prosternal teeth.

It should be noted that normally there is a tibial spur on all the legs, but occasionally this is missing on the last pair. The type of P. validus has a very low, rounded projection at the end of the tibia, but in other, specimens the spur is quite distinct and sharp.

I have to thank Mr. T. R. Harris, of Ohakune, for his kindness in sending me a series of specimens of this species.

Haasiella insularis (Haase), 1887.

Henicops insulaiis Haase, Abh. Zool. Mus. Dresden, No 5, p. 36, 1887. Haasiella insularis Pocock, Ann. May. Nat. Hist., ser. 7, vol. 8, p. 449, 1901; Archey, Trans. N.Z. Inst., vol. 49, p. 316, 1917.

I am now able to give Haase's diagnosis of this species. The locality is Auckland Islands, not Auckland as stated by Pocock and myself.

“Colour greyish-brown, tergal plates with dark margins and a median black patch, head reddish, ventral surface greyish. Head emarginate anteriorly. Prosternum of prehensors armed with 5 + 5 teeth. Tergal plates, especially the anterior ones, margined. Single coxal pores round and large. Length of body, 12 mm.” (Haase.)

– 183 –

In addition, Haase describes the penultimate pair of legs as the longest, with 2-jointed metatarsus and 3-jointed tarsus; the last legs have an undivided metatarsus and a peculiar club-shaped tarsus, formed, it is thought, by the fusion of the terminal claw with the tarsus. Only a single much-mutilated specimen is known.

Scolopendromorpha.

These notes on the Scolopendromorpha are intended as a preliminary revision of the New Zealand members of the order, and therefore descriptions of New Zealand species published in papers abroad are quoted in full. The species recorded herein are from very few localities, and many more areas must be searched before anything like a complete revision can be attempted. That the South Island is better represented than the North Island with regard to the new species of Cryptops described is due to the energetic collecting of Mr. T. Hall and Mr. T. B. Smith, to whom my thanks are due.

Cryptops spinipes Pocock.

Cryptops spinipes Pocock, Ann. Mag. Nat. Hist., ser. 6, vol. 8, p. 156, 1891. C. setosus Pocock, ibid., p. 157. C. spinipes Kraepelin, Mit. Mus. Hamburg, vol. 20, p. 49, 1903; Arkiv. Zool., vol. 10, No. 2, p. 2, 1916; Chamberlin, Bull. Mus. Comp. Zool. vol. 64, p. 4, 1920.

The following is a translation of Kraepelin's description (1903):—

“Hinder end of the head overlapped by the anterior end of the 1st tergite, or conversely with its hinder end overlapping the edge of the 1st tergite, more or less distinctly punctured, generally with two median longitudinal sulci. First tergite with curved outline, with the collar-suleus parallel to the anterior border, punctured like the other tergites; often with a small median depression just behind the middle, without median longituninal sulci. Median longitudinal sulci first beginning on the 3rd or 4th tergite, lateral sulci on the 4th. Median keel not prominent. Anterior margins of prosternum of toxicognaths lightly convex with 5 or 6 setae on either side. Sternites normally punctured. Spiracles slit-like, that of the last segment narrow-oval. Coxopleurae caudally roundly truncated, with scattered spines or setae, pores numerous, reaching to the hinder end. Legs, in the hinder segments, armed with spinescent setae. Ventral surface of the femur of the anal legs with bare longitudinal area between the spines, patella the same, dorsally without longitudinal groove, produced at the end into a small tubercle. Tibia ventrally with 8, 1st tarsal joint with 3 or 4 teeth, the end of the tibia dorsally with a distinct spine on each side. Colour ochraceous. Length, 24 mm. Australia (Sydney), New Zealand.

C. setosus Poc. from New Zealand is only established through its greater hairiness and puncturing, both characters of such great variability that they cannot be considered specific.”

I have only one specimen of this species, collected at Cheviot by Mr. J. B. Maync.

There is a dried specimen of this species in the Canterbury Museum, with, however, no record of locality. It was probably on account of this specimen that Hutton included the species in the Index Faunae Novae Zelandiae, and it seems more likely that it was an immigrant than a native species. It differs from the typical E. platycephalus in the following details: Fifth, leg with 2 tarsal spines (1st to 4th legs missing); the left coxopleura with 3 spines dorsally, the right with 2. (The coxopleurae extend beyond the last sternite by twice the length of that sternite, and meet together behind in the usual manner.)

The Canterbury Museum has a specimen found at Christchurch in 1901 among timber imported from Australia. E. platycephalus, noted above, was probably introduced into this country in a similar manner.

Colour: Head and 1st tergite reddish-brown, remainder dark olive-brown; legs yellowish on proximal half to green distally, distal portion of anal legs light blue, the blue and green fading out in spirit.

Head smooth, sparsely punctured, with 2 median longitudinal anteriorly diverging sulci extending from the posterior border nearly to the middle of the head. Post-cephalic plates moderately large and quite distinct. Posterior border of the head angular, the tip engaged under the 1st tergite. Antennae 17 joints, the proximal 5 smooth, the remainder pubescent. Prosternum of prehensors smooth, sparsely punctured, with irregular transverse sulcus in anterior third. Dental plates very slightly narrowing cephalad, teeth 4 + 4, the outer one slightly apart.

Tergites: the 1st smooth and sparsely punctured, 2nd to 20th distinctly bisulcate. Margining beginning faintly on the 5th (6th), distinctly on the 7th. From 4th or 5th the posterior border is slightly wrinkled and somewhat darker. Last tergite without median sulcus and produced roundly backwards. Sternites bisulcate from 2nd to 20th, the 21st with a weak median sulcus or depression, and strongly narrowed posteriorly. Spiracles very narrowly triangular, slit-like.

Coxopleurae (figs. 16 and 17) with narrow 2-spined conical process, generally without small lateral spine,* pore-area extending partly along process, the pores very fine and close-set. Anal legs: femur (fig. 17) outer ventral with a single row of 3 spines, inner ventral with an oblique row of 3 spines leading to 2-spined angular spur, inner dorsal 2 spines. Terminal claw with basal spur (fig. 18).

Length, to 110 mm.

Loc.—Whangarei, Ruapekapeka, Gisborne; a specimen was caught in 1901 at Southbridge, in a railway-truck containing timber from the Kaipara district.

Hab.—New Zealand, Tasmania, New South Wales, and Queensland.
